Paul Murray’s second novel, Skippy Dies—recently longlisted for the Booker Prize—is more than six hundred pages long and tackles subjects ranging from string theory to World War I. Set at an Irish boarding school, the darkly comic tale (Skippy actually does die in the first chapter) is populated by a sharply drawn cast of confused, self-destructive teens and self-involved, irresponsible adults. Recently, Murray spoke to me from his home in Dublin.

Did you draw any of the characters and themes from your own experiences? Were you bullied at school?

I went to quite an illustrious school in Ireland called Blackrock College, and Seabrook College, the school in the book, physically resembles the school that I went to. But other than that, it wasn’t hugely autobiographical. I wasn’t bullied or anything; I wasn’t brutalized in any way. There were much nerdier kids in my school, and they would draw more of the fire, but I could see it going on around me. It wasn’t an evil place. But there was such a limited view of the world. It was a big rugby school, and I was incredibly bad at rugby. They would make you play it until you were about fifteen, no matter how incredibly pointless that was. So if you weren’t any good at rugby, then you sort of didn’t really have any kind of standing in the school.

I think being a teenager is really, really hard. You’re caught in this double bind: You’re struggling to establish your own identity, and at the same time you have absolutely zero of the tools that you need. You’re completely dependent on your parents, you have no money, and your day is mapped out for you from beginning to end. My school was a boys’ school; there were no girls, so life really felt kind of pointless in that regard. You’ve got these huge sexual transformations happening, but if there are no girls, obviously all the energy is just going to be turned into brutalizing whoever is smaller than you.

There was also a real emphasis on grades. The school would push students to perform well on exams and get a lot of points and get into good universities and so forth. The education system in Ireland is a real sausage factory. You go into class and you learn as many facts as you can and you regurgitate them in your exams, and there’s not a huge amount of respect for learning or a huge amount of respect for education. And because a lot of the kids were quite wealthy, some of them looked down on teachers. And the combination of a might-makes-right brutality and also getting a glimpse of the economic hierarchy that held sway in the country—all those things were really disappointing lessons to learn as a kid. It felt like my life began as soon as I left school.
